What are the various types of refrigeration cycles?
Absorption & vapor compression.
What is the state of refrigerant entering the compressor of a refrigeration system?
low temperature low pressure vapor
What is the refrigerant entering the metering or expansion device of a refrigeration system?
superheated vapor
What is the Refrigerant entering the compressor of a refrigeration system is a?
low temperature low pressure vapor
Coefficient of performance of Vapor compression and Vapor absorption system?
For vapor compression: beta= Qdot / Ẇ =(h1-h4)/(h2-h1)
How do you improve the performance of vapor compressor refrigeration cycle?
In practical applications, vapor-compression refrigeration systems are the most commonly used refrigeration systems, and each system employs a compressor. In a basic vapor compression refrigeration cycle as shown in Figure 3.28, four major thermal processes take place as follows: • evaporation, • compression, • condensation, and • expansion.
What is the state of refrigerant entering the compressor of the refrigeration system?
low temperature low pressure vapor
What did Ferdinand Carre invent in 1858?
He invented the ammonia vapor-compression system used in refrigeration.
What is the state of the refrigerant entering the compressor of a refrigeration system?
low temperature low pressure vapor
Why is refrigerant vapor re introduced to the refrigeration system before refrigerant liquid?
To endure that the ONLY gas in the system is refrigerant.
Why rectifier used in vapor absorption system?
Rectifiers are used to remove water vapor mixed with ammonia vapor if any by cooling it before entering inside evaporator
What component of a refrigeration system changes a high pressure vapor to a high pressure liquid?
Metering device
